The ALCATEL 3AL78856BC is an L-4.1N single-port STM-4 long-haul optical interface card for the Alcatel-Lucent 1640FOX and 1660SM SDH platforms, fitted with an FC/PC connector. It supplies a single STM-4 (622 Mbit/s) optical aggregate or tributary port with the extended reach and higher launch power of the L (long-haul) class, letting operators extend SDH rings over longer spans than the short-reach S-4.1N equivalent. The card shares its slot position and mechanical footprint with the rest of the 1660SM single-port STM-4 optical card family, and is commonly used on 1640FOX customer-premises nodes where a single long-reach STM-4 uplink is required. Tech-Star (UK-based, shipped worldwide) stocks tested ALCATEL 3AL78856BC cards for engineers maintaining Alcatel-Lucent SDH transport. Get in touch to confirm stock and compatibility.
